CALENDAR. Y 1i Specification of Letters Patent.

Patented May 24, 1921.

Application led August 19, 1918. Serial No. 250,624.

To cZZ whom it may concern:

Be it known that I, HENRY LAWRENCE GULLiNn, of the town of Bordeaux, in the any seven contiguous columns.

Province 'of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Calendars; and I hereby de-,

clare that the following is a full, clear, and exact description thereof.

My invention relates particularly to per-4 petual calendars, and has foriits object to provide a calendar of the type adapted to expose the actual number of days in any month; another object being to'simplify and reduce the thickness. of these calendars.

To this end the invention maybe said to consist of a perpetual calendar comprising a.V

rotary disk for the naines ofthe months and an endless flexible loop for the ordinal num-A bers in columnar arrangement and including sufcient columns with relative ordinal numbers to present a complete month in This loop is caused to move slidably across the disk and the disk is adapted to be rotated, while a.

transparent face-plate covers the disk and loop and slidable series of screens are adapted to conceal the surplus ordinals when the month is less than thirty-one days. This mechanism is contained within a substantially tlatccase the fropt of which has openings to expose the monthly ordinals and tie names of the month, the back of the case carrying all the mechanism.

Ther invention also consists of the construction, specific` combination. and particular arrangement of parts, hereinafter described with reference to the drawings and pointed ont in the claims.

For full comprehension, however, of my invention reference must be made to the accompanying drawings in whichy lligure l is a trontelevation of my improved calendar;

Fig. 2 is a vcrticalsertional view taken on line 2- 2 Fig. l; y

Fig. 3 is a horizontal section taken on line 3?) Fig. '1, and

Figs. i and 5 are detail views of the back and one of the slidable screensrespectively..

stance, or an eye f by which it may be hung on the wall. lVithin the case, according to my inventionand on the back c, is mounted a rotary disk g bearing the names of the months including two Februarys one having the numberf28 and word days beneath it and thek other the words leap year; while the other l*months of the year have their number of kdays indicated beneath their names. An endless iiexible loop c,`p`refer ablyof textile ribbon, incloses the disk, and is divided transversely into thirteen spaces on, each containing a series of ordinal numbers arranged to expose, through an opening Z in the front ofthe case, a full monthly.'

calendar, with the ribbon in any position to which it may be adjusted. The front of the' ing just mentioned, through which the names and associated inscription of the'number of the days of the month, arekexposed. The back c of the case carries the disk pivotally, the pivot p projecting through the back and being provided with a thumbhold to facilitate its operation kmanually. vThe ribbon loop is slidablysupported by a pair of guiding carriers rconsisting of wires bent to wide Usform with their ends s turned out and set in notches t in the opposite edges of the back, this ribbon being operated by a stud u carried thereby and projecting through a slot 'v in the back.

In order to conceal the surplus ordinals to confine the dates to the actual number of days of the month exposed, a series of slidable screens w with their top ends bent outward to afford linger holds are carried in slots g/ in a transparent face-plate 2 the slots being cut with enlarged ends `3 to present shoulders acting as stops for limiting the movement. The lower shoulder in each slot being engaged by tits 4 pressed out of the screens near their lower ends and a sufficient distance above the ends. to prevent the displacement of such ends from the slots kwhen the screen is raised to the limit of'its vertical movement. VThe finger holds are adapted to rest on the lower edge of the opening Z in the front when, the screens. are lowered. This transparent faceplate is fastened to the back by eyelets 10 and it is of sufficient size to extend completely across those portions of the disk and ribbon. exposed to dust or dampness through the openings Z and its function being to also prevent interference of the edges of the ribbon and the disk with the edges of the openings; the uppermost of the slots 3/ being preferably located in close proximity to the bottom edge of the opening Z.

In order to cause the calendar to stand evenly a pair of feet 12 are provided at its bottom corners by pins having spherical heads, these pins being stuck into the lower edge of the back at these bottom corners, the spherical. heads serving as feet.

When the disk has been rotated to an angular position exposing the name of the month through the opening 0 and the ribbon shifted to bring the first day of the month in uXta- Y position with the particular day of the week upon which the month. starts (indicated at the top of the opening Z) the ordinal numbers of a complete month of thirty-one days are exposed, which is obtained by the particular arrangement of ordinal numbers and spaces illustrated. In the event of the month having less than thirty-one days the screen or screens necessary to conceal the surplus ordinals are adjusted for the purpose.

To meet the requirement of leap year the disk is as before mentioned provided with two Februarys one of whiehhas the words leap year associated with it and the angular position of the disk is changed to expose this-leap year February. ln this case Vthe ordinal number 29 will not be screened.

Zith the construction and particular arrangement of parts above described a case of minimum thickness may be contained, while the fact 4that operating parts are carried by the back simplifies the assembling of the calendar which is further simplified by the flexibility or resiliency of theV back with its slotted side edges in which the ends s ofthe ribbon carriers fr are set. To equip the back with a slidable ribbon it is curvedto bring the `edges closer together the carriers with the ribbon looped about them may then be readilyset in the notches` t and when the back is released and springs to its flat position the carriers are drawn inwardly to their seats and the ribbon stretched taut, the stud engaging in and projecting through theslot 'u in the back.

What I claim is as follows l. In a perpetual calendar, a movable member bearing ordinal numbers divided in series, any contiguous seven ofwhich series include thirty-one days, a front for concealing a portion of said movable member and having an opening for exposing such contiguous series, of means for concealing one or more of the ordinal numbers finishing the l dependently supported in position to be adjusted over the said ordinal numbers finishing the month the screens consisting of strips of metal each having one end bent to serve as a finger hold, for the purpose set forth.

3. In a perpetual calendar the combination with a front member having an opening the-rein for exposing to view the days of the month, anda back member each vertical side edge ofwhich is provided with a pair Aof notches; of a flexible endless loop bearing ordinal numbers divided in vertical series, anyv contiguous seven of which include thirty-one days; and means for carrying said loop, said means consisting of a pairof guiding carriers of substantially wide U-form located at opposite sides of said opening and each having its free ends projecting through said notches and offset to prevent displacement therefrom.

" 4t. In a perpetual calendar a rotary disk liiearing the names of the months ofthe year;

a movable endless loop bearing a plurality of related series of ordinal numbers any' seven of which. series Vpresent the ordinal numbers of a complete month of thirty-one days; a front concealing portions of the loop and 'disk and having openings exposing some ofthe ordinal-number series and one of the month-names a transparent protective cellu loid face-plate located between the front, ou one hand, and the loop and disk on the other hand and having a series of pairs of parallel slots y/ with enlarged ends; and a series of' metal screenscarried slidably in the pairs of parallel slots and each having its upper end bent outwardly to afford a finger hold and slidable in a direction .at substantially right angles to the direction of travel-of the ribbon.

In. testimony whereof I have signed my name to this specification in the presence of two witnesses.

Witnesses L. C. TWINTER, G. Tnnenow.
